© 2016 IEEE. This paper presents a coupled field-circuit analysis method for the high temperature superconducting (HTS) cable considering magnetic hysteresis by using the improved extended finite element method (XFEM). The quasi-3D cylindrical coordinate HTS cable model is firstly proposed based on the shell element theory. The quasi-3D meshing elements are used instead of the traditional 3D meshing elements to overcome the difficulties in meshing. A new Preisach type hysteresis model of HTS tapes is firstly combined with the improved XFEM to determine the magnetic hysteresis inductance. The numerical simulation results of this field-circuit coupled method are reported compared with the experimental test results for the case of an HTS cable with 2 layers.
